7 2/5 + 2 1/2 = 9 9/10
You'd just times the denominators to a common number which would be 10 and the the numerator would be added together as 6 and 3. Then you end up with 9 9/10 as a mixed number
F: y=1.30x+5 G: y=7x+3 H: y=1.80x-1 J: 1.75x+0.16y I know F G and H are correct but I’m not really sure about J but I think the setup up is kind of right but I don’t know about that one
The compound inequality would be
0.23≤x≤1.63.
The graph would have a number line marked at least from 0.23 to 1.63; both of these numbers would have a filled in circle over them, and the area of the line between them would be shaded.
We must find the amount of tax for each city and each purchase amount:
9.75%=9.75/100 = 0.0975
0.0975(11.57) = 1.13
0.0975(81.43) = 7.94
7.75% = 7.75/100 = 0.0775
0.0775(11.57) = 0.90
0.0775(81.43) = 6.31
To find the differences in the tax amounts, we subtract:
1.13 - 0.90 = 0.23
7.94 - 6.31 = 1.63
Answer:
168 square inches
Step-by-step explanation:
Assuming these are the dimensions of a rectangular prism, then the surface area is given by
TSA=2(lw+lh+wh)
We substitute the dimensions into the formula to obtain:
TSA=2(2*9+2*6+9*6)
We simplify to get:
TSA=2(18+12+54)
TSA=2(84)
TSA=168 square inches
Try this solution; note, this way is not the shortest one.
